The best exhaust fans promote air quality and ventilate enclosed spaces. It keeps the air fresh and the room cool. It removes unwanted scents, hot air and moisture including other contaminants. Exhaust fans come in different shapes and sizes to fit any room. Modern designs now eliminate the noise caused by the fan blades.

Here are a few important factors to consider when buying a commercial exhaust fan:

1. Size and Capacity

There are many models of exhaust fans used for a variety of applications. Manufacturers have to develop different models for different needs. The buyer has to sort through the various models to find an exhaust fan that is suitable for their needs and that will fit in their facility.

Choosing an exhaust fan depends on the size of the room. The exhaust fan’s ability to move volumes of air is rated in meters cubed per hour. Higher rating expels more air. Larger exhaust fans are not always a better option. If the facility is large, the rating has to be high. However, if the facility is small, a less powerful exhaust fan will work perfectly well.

2. Usage

Exhausts fans are used for both commercial and residential purposes. They are integrated into the HVAC systems of facilities. Common areas of usage include the kitchen and bathroom where the room can be filled with steam that results in mold and mildew. High humidity can damage building materials, result in structure rot and peel paint.

The installation of an exhaust fan can help to reduce the steam, mold development and odors that are dispersed harmlessly to the outside. Another benefit of an exhaust fan is that it can control temperatures. It is extensively used during hot months to draw in cooler air from the outside.

3. Noise Level

Exhaust fans can be very noisy and annoying. However, newer models are much quieter than before. Sone is the metric used to measure sound. One sone is like the sound you hear from the refrigerator. The higher the sone, the noisier the fan. When buying an exhaust fan seek a model with a sone rating of two or less.

4. Energy Efficiency

Consider an exhaust fan that is energy efficient as these systems can operate continuously at times. Less energy usage means that you pay less in utility bills. For commercial properties, an efficient exhaust fan can lead to a reduction in building operational costs and less environmental impacts. Today there are exhaust fans that come with a sensor to control its usage and to promote energy efficient ventilation when needed. Look for models that offer low sound emission and have a low wattage consumption.

5. Features

The latest model of exhaust fans come with various features such as a built-in light, sensors, rust proof engineering, energy efficient temperature control and night light. Newer models are certified conforming to rigorous energy efficient standards. New models are also slim, compact, easy to install and economical to run.

6. Healthy and Hygienic Lifestyle

Ventilated rooms promote a healthy and hygienic lifestyle. Smoke, toxic fumes, smell, steam and other air pollution can remain in a room in which families live that can result in health problems. People spend most of their time indoors especially when dealing with harsh weather conditions. Indoor air pollution can result in health risks. You will also know when you have a ventilation problem when you experience a lingering odor, hot air or see mold and mildew form on the ceilings or exterior walls.

The only way to promote a healthy environment is to expel the polluted air and replace it with clean air circulation.  Opening windows is one solution, but if it is raining or cold, the windows have to remain closed. With an exhaust fan, the windows can remain closed, while the air is changed gradually making the room more comfortable for the occupants
